CC -!- FUNCTION: Dual specificity protein kinase which acts as an essential
CC component of the MAP kinase signal transduction pathway. With
CC MAP3K3/MKK3, catalyzes the concomitant phosphorylation of a threonine
CC and a tyrosine residue in the MAP kinases p38 MAPK11, MAPK12, MAPK13
CC and MAPK14 and plays an important role in the regulation of cellular
CC responses to cytokines and all kinds of stresses. Especially,
CC MAP2K3/MKK3 and MAP2K6/MKK6 are both essential for the activation of
CC MAPK11 and MAPK13 induced by environmental stress, whereas MAP2K6/MKK6
CC is the major MAPK11 activator in response to TNF. MAP2K6/MKK6 also
CC phosphorylates and activates PAK6. The p38 MAP kinase signal
CC transduction pathway leads to direct activation of transcription
CC factors. Nuclear targets of p38 MAP kinase include the transcription
CC factors ATF2 and ELK1. Within the p38 MAPK signal transduction pathway,
CC MAP3K6/MKK6 mediates phosphorylation of STAT4 through MAPK14
CC activation, and is therefore required for STAT4 activation and STAT4-
CC regulated gene expression in response to IL-12 stimulation. The pathway
CC is also crucial for IL-6-induced SOCS3 expression and down-regulation
CC of IL-6-mediated gene induction; and for IFNG-dependent gene
CC transcription. Has a role in osteoclast differentiation through NF-
CC kappa-B transactivation by TNFSF11, and in endochondral ossification
CC and since SOX9 is another likely downstream target of the p38 MAPK
CC pathway. MAP2K6/MKK6 mediates apoptotic cell death in thymocytes. Acts
CC also as a regulator for melanocytes dendricity, through the modulation
CC of Rho family GTPases (By similarity). {ECO:0000250}.

CC -!- ACTIVITY REGULATION: Activated by dual phosphorylation on Ser-207 and
CC Thr-211 in response to a variety of cellular stresses, including UV
CC radiation, osmotic shock, hypoxia, inflammatory cytokines, interferon
CC gamma (IFNG), and less often by growth factors. MAP2K6/MKK6 is

CC -!- DOMAIN: The DVD domain (residues 311-334) contains a conserved docking
CC site and is found in the mammalian MAP kinase kinases (MAP2Ks). The DVD
CC sites bind to their specific upstream MAP kinase kinase kinases
CC (MAP3Ks) and are essential for activation (By similarity).

CC and is required for the binding to MAPK substrates. {ECO:0000250}.
